When a child eats a coin into the stomach, it is recommended to go to the hospital for an x-ray to determine the location of the coin. If it is inside the stomach and you want to deal with it aggressively, you can remove the coin by means of gastroscopy. It is also possible to treat the coin conservatively for the time being, because the coin is relatively round and smooth, and it is usually rare to puncture the gastrointestinal tract or mucous membranes, which can lead to bleeding. You can take oral diarrhea drugs, such as senna, mannitol diarrhea, try to let the coin through the anus as soon as possible out of the body. If the coin is not expelled after a few days, the x-ray must be reviewed periodically. If the coin stays in a certain place for a long time without moving, it is possible that the coin has damaged the local mucosa in that place, and local adhesion or rupture of the mucosa occurs, which will lead to rupture and bleeding of the gastric mucosa or intestinal mucosa in a long period of time, and perforation will occur in severe cases, which will lead to serious complications. If the child has persistent abdominal pain, this may be the case, and should be treated actively by removing the coin through gastroenteroscopy, or through open surgery.
